A novel NOAA climate observatory with a unique past arrived at Cape Canaveral on Thursday to begin two months of launch preparations, testing, and fueling before liftoff aboard a SpaceX Falcon 9 rocket.

The Deep Space Climate Observatory — known as DSCOVR — was transported by truck fr om NASA's Goddard Space Flight Center in Maryland to an Astrotech satellite processing facility in Titusville, Fla., just outside the gates of Kennedy Space Center.

The spacecraft arrived Thursday, and engineers planned to unpack the satellite inside a clean room to prepare DSCOVR for launch.

Workers will hand over the 1,256-pound (570-kilogram) satellite to SpaceX in January for attachment to the company's Falcon 9 launcher at Cape Canaveral's Complex 40 launch pad. Liftoff is targeted for Jan. 23.

DSCOVR is a joint project between NOAA, NASA and the U.S. Air Force. The satellite will be positioned at the L1 libration point a million miles away fr om Earth, wh ere its instruments will monitor space weather and the solar wind for a planned five-year mission.

A swarm of charged particles approaching Earth from the sun can interfere with transportation and electrical infrastructure. A report by the National Research Council in 2009 concluded a large solar storm impacting Earth could cost between $1 trillion and $2 trillion, and it could take up to a decade to recover from the event.

"We must always stay on top of developing solar storm activity and provide accurate, timely forecasts," said Mike Simpson, the DSCOVR program manager at NOAA. "DSCOVR will extend our capability to do that."

The spacecraft will serve as a sentinel to warn scientists on Earth of approaching solar storms, giving up to an hour of lead time to inform commercial airlines, electric utility operators, and communications and GPS users of a potential disruption.

NASA's aging Advanced Composition Explorer — launched in 1997 and operating well beyond its design life — is currently the only spacecraft capable of supplying such warning to NOAA's space weather forecast team.

"The instruments on DSCOVR will improve upon what we have with ACE, as they will continue to operate even during severe space weather storms. The DSCOVR data will also be used to drive the next generation of space weather models, allowing forecasters to specify wh ere on Earth the storm conditions will be at their worst," said Doug Biesecker, DSCOVR program scientist at NOAA's Space Weather Prediction Center in Boulder, Colo.

The DSCOVR spacecraft was originally developed for launch in the late 1990s for the Triana mission, a NASA-led project to study Earth's climate and how much solar energy was being absorbed and reflected by Earth. Named for the sailor who first spotted land on Columbus's 1492 voyage to the Americas, the Triana mission had its genesis in an initiative backed by former Vice President Al Gore, who in 1998 proposed launching a satellite on the space shuttle to record live around-the-clock imagery of Earth from deep space.

NASA suspended work on the Triana mission in 2001, then canceled the project in 2005, citing the dwindling number of remaining shuttle flights and a lack of funding to refurbish and launch the satellite.

NOAA saw a use for the Triana spacecraft, which NASA kept under climate-controlled storage at Goddard for seven years, when scientists noticed a potential gap in solar storm warnings as the ACE satellite outlived its planned lifetime.

Engineers took the spacecraft out of storage and put it through testing and modifications for launch on unmanned rocket.

DSCOVR still hosts the Earth science instruments originally planned for the Triana mission, including a camera to capture true color images of the full disk of Earth every two hours and a sensor to measure how much solar energy affects the planet's climate.

NOAA is in charge of the mission and operating DSCOVR after liftoff, and NASA is overseeing preparations on the spacecraft. The U.S. Air Force agreed to pay for a Falcon 9 rocket to launch the satellite.

A new space weather observatory to be stationed a million miles fr om Earth has been enclosed inside the nose cone of a SpaceX Falcon 9 rocket for liftoff Sunday from Cape Canaveral.
The Deep Space Climate Observatory was filled with maneuvering fuel, tested and verified ready for launch, then encapsulated inside the Falcon 9 launcher's 5.2-meter (17.1-foot) diameter payload fairing at the Astrotech spacecraft processing facility near Kennedy Space Center.
The satellite rolled out of Astrotech on Saturday night for a short road trip to SpaceX's Falcon 9 hangar at Cape Canaveral's Complex 40 launch pad. Once it arrived, the payload housing was tilted on its side and hooked up to the Falcon 9's second stage.
Final testing is underway this week to ensure the refrigerator-sized spacecraft and the rocket work together. The booster should be rolled out of the hangar and erected on the launch pad this weekend.
The Falcon 9 rocket has completed a brief on-pad firing of its nine Merlin 1D first stage engines in a customary preflight test after a practice countdown.
Liftoff of the 22-story rocket is set for 6:10 p.m. EST (2310 GMT) Sunday, about two minutes after sunset on Florida's Space Coast.
The Falcon 9's 15th flight will send DSCOVR on a high-speed trajectory to escape the grip of Earth's gravity.
DSCOVR is a joint project between NOAA, NASA and the U.S. Air Force. The satellite will be positioned at the L1 libration point a million miles away from Earth, wh ere its instruments will monitor space weather and the solar wind for a planned five-year mission.

The Air Force arranged the DSCOVR mission's liftoff with SpaceX, paying the California-based space transportation company $97 million under a launch services contract signed in December 2012.
NOAA is the overall manager of the DSCOVR program, with NASA assisting with satellite preparation and prelaunch processing.
The Air Force signed the DSCOVR launch order — plus a Falcon Heavy launch reserved for multiple defense-related experimental satellites — under the service's Orbital/Suborbital Program 3 (OSP 3) contract, which allows contractors to compete to launch the military's smaller spacecraft.
SpaceX and the Air Force expect to complete certification of the Falcon 9 rocket to launch more critical Evolved Expendable Launch Vehicle-class (EELV-class) national security satellites later this year. The certification will allow SpaceX to compete directly against United Launch Alliance for the military's most expensive communications, navigation and spy satellites.
ULA is not part of the OSP 3 contract, and the incumbent EELV contractor did not bid to launch the DSCOVR mission.
SpaceX plans a second try to recover the Falcon 9 rocket's first stage booster during Sunday's launch. An untried rocket-assisted flyback maneuver on SpaceX's last launch Jan. 10 guided the 14-story booster to a football field-sized barge in the Atlantic Ocean, but the company said the rocket's stabilizing winglets ran out of hydraulic fluid on final descent to a vertical propulsive landing.
The booster crashed on the landing platform, but SpaceX recovered wreckage and returned the debris to port aboard the barge.
The Falcon 9 rocket with DSCOVR carries additional hydraulic fluid to avoid a recurrence of the problem.
Engineers will inspect the Falcon 9 booster if the flyback experiment works as designed on Sunday's flight, determining what work is required to refurbish the rocket for another mission.
SpaceX hopes to make the Falcon 9 rocket's first stage reusable in the future in a bid to cut the cost of space launches.

Forecasters predict mostly clear skies, light winds and comfortable temperatures for Sunday's launch of a Falcon 9 rocket with a NOAA satellite designed to warn of solar storms that could disrupt navigation and communication technology on Earth.
The Deep Space Climate Observatory is set for liftoff fr om Cape Canaveral's Complex 40 launch pad at 6:10:12 p.m. EST (2310:12 GMT) Sunday in an instantaneous launch opportunity.
The launch is scheduled two minutes after sunset at Cape Canaveral, and could create a dusk spectacle as the 22-story launcher rises into sunlight.
The two-stage Falcon 9 rocket will deploy the refrigerator-sized satellite in space about 30 minutes after launch, sending DSCOVR on a high-speed trajectory to escape the bonds of Earth's gravity.
DSCOVR's final station will be at the L1 libration point, a gravitationally-stable location a million miles from the day side of Earth.
A NASA spokesperson said a launch readiness review Friday gave the go-ahead to continue with final launch preparations, including rollout of the Falcon 9 from its processing hangar to the Complex 40 launch pad, wh ere it will be rotated vertical for Sunday's countdown.

The official weather forecast issued by the U.S. Air Force's 45th Weather Squadron on Friday calls for a less than 10 percent chance conditions could violate the Falcon 9 rocket's weather constraints.
"A high pressure area drops south into Florida on Saturday and Sunday, allowing for plenty of sunshine and temperatures near 70 degrees Fahrenheit along the Space Coast," forecasters wrote in a weather summary. "There is very little threat of any launch weather rule violations. Maximum upper winds will be from the northwest at 40 knots near 42,000 feet."
The forecast calls for a few cumulus clouds at 3,000 feet and a layer of scattered cirrostratus clouds at 26,000 feet. Winds will be from the southeast at 8 to 12 mph, and temperature at launch time will be around 68 degrees Fahrenheit.
The only slight chance of exceeding a launch weather constraint will be with the cumulus cloud rule, according to the forecast.
If the launch is delayed to Monday — when the launch time would be 6:07 p.m. EST (2307 GMT) — there is an 80 percent chance of acceptable weather, with the main worry being thick clouds from an approaching cold front.

Engineers worked inside a climate-controlled clean room for two months to ready NOAA's new space weather observatory for launch aboard a SpaceX Falcon 9 rocket.
The Deep Space Climate Observatory, equipped to detect incoming solar storms and give scientists a new view of Earth's climate, will blast off aboard a Falcon 9 rocket from Cape Canaveral. The refrigerator-sized satellite arrived at the Astrotech spacecraft processing facility in November after a road trip from NASA's Goddard Space Flight Center in Maryland.
DSCOVR was originally conceived in the late 1990s by former Vice President Al Gore, but the mission was shelved and the spacecraft placed in storage until the project received a new lease on life.
The photos below show the satellite being unwrapped after shipment to Florida, a light test to check out its power-generating solar arrays, and preparations to be enclosed inside the Falcon 9 rocket's 43-foot-tall two-piece payload fairing.

The world's most distant weather outpost is set for liftoff fr om Cape Canaveral on Sunday aboard a SpaceX Falcon 9 rocket, launching to a point a million miles fr om Earth to warn forecasters of solar storms that could disrupt global air traffic, satellite navigation and power grids.
The Deep Space Climate Observatory, a $340 million mission supported by NOAA, NASA and the U.S. Air Force, will detect waves of solar wind approaching Earth that could generate powerful geomagnetic storms around Earth.
"DSCOVR will be the nation's first operational space weather mission in deep space," said Tom Berger, director of NOAA's Space Weather Prediction Center in Boulder, Colorado. "It will be located at the L1 point one million miles from Earth, wh ere it will orbit between the Earth and sun continually."
Launch of the refrigerator-sized satellite is set for 6:10:12 p.m. EST (2310:12 GMT), and a Falcon 9 rocket will heave the 1,256-pound spacecraft on a high-speed trajectory breaking the bonds of Earth's gravity.

Спойлер

Deployment of the satellite from the Falcon 9's upper stage is planned about 35 minutes after liftoff.
"DSCOVR, when it launches, will take about 110 days to get to its observing point, which is kind of a unique place for us," said Stephen Volz, assistant administrator for NOAA's satellite and information service. "It's the first deep space observer we have. It will be sitting at what's called a Lagrange point, which is a gravitationally stable point about a million miles away from the Earth directly in line with the sun."
On the way, the spacecraft will extend its power-generating solar panels, deploy a boom holding a magnetometer sensor, and undergo testing of its systems and space weather instruments.
A mid-course correction maneuver is planned about 31 hours after liftoff to fine-tune DSCOVR's path toward the L1 location, wh ere it will again fire its engine to enter a looping halo-like orbit around the Lagrange point.
"From this location, DSCOVR will provide forecasters with critical information about the supersonic solar wind that continually streams from the sun to interact with Earth's magnetosphere and upper atmosphere," Berger said. "Most of us know this interaction through its generation of the aurora borealis, or Northern Lights, the most visible aspect of space weather.
"DSCOVR will also serve as our tsunami buoy in space, if you will, giving forecasters up to an hour's warning of these huge magnetic eruptions from the sun that ocacsionally occur, called Coronal Mass Ejections, or CMEs," Berger said.

DSCOVR's liftoff comes after a saga stretching back a decade-and-a-half, when former Vice President Al Gore proposed a mission to produce live imagery of the full sunlit disk of Earth 24 hours a day. The pictures were to be posted on the Internet.
The mission was named Triana, after the sailor that first spotted land on Columbus's 1492 voyage to the Americas. It was supposed to launch on the space shuttle, and was once manifested to fly on the space shuttle Columbia's STS-107 mission, which ended with the ship's destruction and the loss of its seven-person crew in February 2003.
But the spacecraft was mothballed in 2001 after it came under criticism from Gore's political rivals, and NASA canceled the Triana mission 2005, citing the dwindling number of remaining shuttle flights and a lack of funding to refurbish and launch the satellite.
Engineers removed the spacecraft from storage in 2008 after officials identified the disused platform as a potential affordable way to replace NASA's aging Advanced Composition Explorer, which launched in 1997 and is now well beyond its design life, as a source of solar wind data.
NOAA renamed the craft the Deep Space Climate Observatory, or DSCOVR, and joined forces with NASA and the Air Force to put it into space.
NASA was responsible for refurbishing the spacecraft — using funding from NOAA — and spent its own money to ready DSCOVR's Earth watching instruments for launch. The Air Force signed a $97 million contract for SpaceX to launch the satellite on a Falcon 9 rocket.
Instead of gearing the mission toward looking back at Earth, DSCOVR will point a plasma magnetometer into the constant flow of atomic particles streaming away from the sun to measure the velocity, magnitude and direction of the solar wind's magnetic field.
"What we've had is a swap of primary mission objectives," said Steven Clarke, director of NASA's joint agency satellite division, which oversees joint projects between the space agency and NOAA. "Triana was primarily focused on Earth observing and Earth science, with space weather being secondary, and now space weather is the primary objective for DSCOVR. We did have space weather instruments on-board for Triana, but now they become the primary objective for this mission."

Triana's two Earth observing sensors — a camera named EPIC and a radiometer named NISTAR — are still aboard DSCOVR. They will collect imagery and scans of the sunlit side of Earth from a new viewpoint a million miles away.
"Together these instruments will give us new insights into air quality, land cover change and climate change," said Richard Eckman, DSCOVR program scientist at NASA.
The EPIC camera built by Lockheed Martin's Advanced Technology Center will produce a full-color image of the day side of Earth every four-to-six hours, Clarke said, and the imagery will be posted on a publicly accessible website within 24 hours.
The camera's more scientific purposes include monitoring total ozone and aerosols in Earth's atmosphere, cloud height and vegetation properties in 10 narrow-band channels in ultraviolet, visible and infrared wavelengths.
"I think it will be an inspiration for people to see the sunlit disk, when they can go online and take a look at something that was just taken from a unique vantage point roughly 24 hrs before," Clarke said.
The NISTAR instrument, manufactured by Ball Aerospace in partnership with the National Institute of Standards and Technology, will take an accounting of how much radiation is reflected and emitted off Earth. Scientists say it can help determine how much of the energy comes from human activity.
"The L1 vantage point of Earth, in which we can observe the entire sun-facing side of Earth — and all in one view — will essentially eliminate the sampling issues encountered by other low Earth orbiting satellites that are measuring the radiation budget," Eckman said.
"This measurement should improve our understanding of the effects of changes in Earth radiation budget caused by human activities and natural phenomena," Eckman said.
Francisco Valero, a researcher at the Scripps Institution of Oceanography in San Diego, led the original science team before the DSCOVR mission's cancellation.
In a 2009 interview with Spaceflight Now, Valero said the mission's holistic view of Earth would give scientists a better picture of how the planet actually works.
"I am not watching, say, San Francisco, then 10 hours later, New York, and then Denver," Valero said, referring to how satellites in low Earth orbit make their observations. "I'm looking at the whole thing now."
The new paradigm demonstrated by DSCOVR should be more reliable because using low Earth orbit satellites is like "looking at the forest tree by tree," said Valero, who now works as a senior adviser and planner on the DSCOVR team, according to a release posted on the University of San Diego's website.
Volz said the DSCOVR mission represents a "set of firsts" for NOAA, marking the agency's first deep space observing platform and its first launch with SpaceX.
The spacecraft will beam back data on the solar wind in real-time, allowing forecasters in NOAA's Space Weather Prediction Center to issue alerts and warnings when conditions could threaten infrastructure in communications, navigation and electrical utilities.
"As society continues to become more reliant on technology in all aspects of our lives, and because of the impact of space weather as a real threat, we must have a constant, reliable and timely flow of space environment information," said Doug Whitely, deputy director of the office of systems development in NOAA's satellite and information service. "With DSCOVR data replacing that of ACE, NOAA's Space Weather Prediction Center will continue providing critical services by monitoring solar activity and providing geomagnetic storm forecasts and warnings."
NOAA's space weather forecast office issues "nowcasts" and alerts to more than 44,000 individuals and organizations signed to receive the notices via email. Data from DSCOVR will help scientists make forecasts for future space weather events with more geographic precision.
"Effects of space weather are wide-ranging, with potentially significant consequences. Every major public infrastructure system, including satellites, GPS, aviation and the electric power industry is at risk from space weather," said Doug Biesecker, DSCOVR's program scientist at NOAA.

 Technicians are putting the finishing touches on a Falcon 9 rocket set for liftoff Sunday with a NOAA satellite built more than a decade ago, put in storage and resurrected to give early warning of solar storms.
The Deep Space Climate Observatory is set for launch at 6:10:12 p.m. EST (2310:12 GMT) Sunday aboard a Falcon 9 rocket from Cape Canaveral's Complex 40 launch pad.
The 224-foot-tall rocket will send the refrigerator-sized satellite on a high-speed path to break free of Earth's gravity, heading for a position one million miles away at the L1 Lagrange point, a gravitationally-stable location lined up between the Earth and the sun.
It will take about 35 minutes for the Falcon 9 rocket to give DSCOVR the boost necessary to reach its target.
The $340 million mission is a partnership between NOAA, which leads management of the program, and NASA and the U.S. Air Force. NASA was responsible for refurbishing the satellite and readying it for launch -- with funding from NOAA -- and the Air Force is paying SpaceX about $97 million for the launch itself.
"The spacecraft is in great shape," said Steven Clarke, director of NASA's Joint Agency Satellite Division. "We're not working any issues at this time, final closeouts will occur later today, and we're looking forward to SpaceX providing DSCOVR a great ride tomorrow evening on its journey to L1."
DSCOVR was originally conceived in the late 1990s as the Triana mission, which was heralded by former Vice President Al Gore as a way to raise awareness of climate issues among the public.
Triana was canceled in the early 2000s, and the finished spacecraft was put into storage at NASA's Goddard Space Flight Center in Maryland until 2008, when it was reactivated and tested for a new goal of measuring the incoming solar wind and give warning of events that could disrupt communications, navigation, satellite operations and power grids.
Sunday's launch will mark SpaceX's first launch beyond Earth orbit, and it is the second Falcon 9 flight of the year.

 The 224-foot-tall Falcon 9 rocket has been rolled out and rotated vertical atop Cape Canaveral's Complex 40 launch pad, aiming for liftoff at precisely 6:10:12 p.m. EST (2310:12 GMT).
Workers then began plugging into electrical and propellant lines ahead of the start of the countdown today.
No problems are reported at this stage in the launch preparations. Fueling of the two-stage rocket with RP-1 fuel -- a highly-refined kerosene -- and liquid oxygen should begin shortly after 3 p.m. EST (2000 GMT).
The rocket is one of the tallest in the world. The Falcon 9's first and second stages measure 12 feet in diameter, and the SpaceX-built payload fairing housing the Deep Space Climate Observatory spacecraft is 17 feet in diameter (5.2 meters) and 43 feet tall.
Today's flight marks the 15th launch of a Falcon 9 rocket since debuting in June 2010. It's the 10th mission of the improved Falcon 9 v1.1 version, which made its inaugural launch in September 2013 from Vandenberg Air Force Base.
The weather outlook for today's launch calls for a 90 percent chance of favorable conditions.

 At launch time, forecasters predict near-ideal conditions with a few clouds at 3,000 feet and scattered clouds at 9,000 feet, and southeast winds at 8 to 12 mph.
There is a 90 percent chance of acceptable weather at the launch time of 6:10:12 p.m. EST (2310:12 GMT).
At this point in the countdown, SpaceX workers should be clearing Cape Canaveral's Complex 40 launch pad in preparation for fueling of the Falcon 9 rocket with kerosene and liquid oxygen propellants.
A poll of the SpaceX launch team is planned for 2:51 p.m. EST (1951 GMT) to give the go for fueling, and propellant will be pumped aboard beginning at 3:11 p.m. EST (2011 GMT).

В первом - студенческий спутник. Во втором - испытательный спутник. В третьем, я ошибся, опять военный спутник и попутная нагрузка от НАСА и частников. В четвертом - успешном - болванка.

Спутники явно дешевые.

Вот потом военные на Маска явно обиделись. В основном, как я понял, потому что они хотели легкую ракету и потому терпели, а Маск переключился на требования НАСА и соперничество с ULA.

 Former Vice President Al Gore is here at the Kennedy Space Center to view the launch of the Falcon 9 rocket with DSCOVR. Gore conceived the idea to send a satellite to the L1 Lagrange point to capture around-the-clock views of the sunlit face of Earth, yielding data on the planet's climate and offering inspirational views accessible to everyone.
"The constant ability to see the Earth -- whole -- fully sunlit every single day, the opportunity for every man, woman and child who lives on the Earth to see -- if they wish -- their own home in the context of the whole, can add to our way of thinking about our relationship to the Earth and, of course, the Earth's ecosystem," Gore said in remarks to reporters moments ago.

ЦитироватьSpaceX отложила запуск научного спутника из-за технических проблем (http://russian.rt.com/article/73189)

Частная американская компания SpaceX отложила запуск климатической обсерватории дальнего космоса. Следующая попытка отправки спутника может быть предпринята уже сегодня в 18:07 по местному времени. Космический аппарат должен извещать учёных о вспышках и бурях на ближайшей к нам звезде, а также вести наблюдения за Землёй.

09.02.2015, 04:33
Как сообщает ТАСС, запуск научного спутника компании SpaceX был задержан из-за технических проблем. Вышла из строя расположенная рядом с космодромом на мысе Канаверал радиолокационная станция, входящая в систему ВВС США по контролю за пуском ракет. Кроме того, возникли проблемы в работе видеопередатчика, установленного на первой ступени ракеты-носителя Falcon 9, которая должна вывести аппарат в космос.

По данным метеорологов, вероятность того, что погода на мысе Канаверал будет благоприятствовать запуску, который должен состояться сегодня, составляет всего 40%.

Спойлер

Спутник под названием климатическая обсерватория дальнего космоса должен через полчаса после запуска отделиться от ракеты Falcon 9 и взять курс на Солнце. Примерно через 110 дней полёта аппарат достигнет своей конечной точки, расположенной в 1,6 млн км от Земли - на полпути между нашей планетой и Солнцем. Оттуда он и будет вести наблюдения за «космической погодой».

Чувствительные приборы будут регистрировать солнечные вспышки, вызывающие геомагнитные бури и изменяющие радиационную обстановку в околоземном космическом пространстве. Это поможет специалистам прогнозировать погоду и на Земле.

На борту DSCOVR размещены также два прибора, которые будут наблюдать за Землёй. Они смогут отслеживать последствия извержений вулканов, пожаров и наводнений, а также проводить озоновые измерения. Спутник также будет делать фотографии Земли, которые будут размещаться в интернете. Аппарат должен проработать на орбите не менее пяти лет. Стоимость проекта вместе с расходами на запуск составит примерно $340 млн.

Во время предстоящего запуска SpaceX снова попытается «поймать» и сохранить первую ступень Falcon9, которая ранее всегда падала в воды Атлантического океана. «Полностью и в короткие сроки возвращаемые ракеты — это то, что никогда не делалось раньше, и то, что является необходимым прорывом для существенного сокращения стоимости космических полетов», — заявили представители компании перед запуском.

10 января компания намеревалась провести эксперимент по посадке первой ступени ракеты на плавучую платформу, расположенную в 322 км от побережья Флориды. Спустя час после старта стало известно, что ступень не смогла успешно приземлиться. «Ракета долетела до космического порта платформы, но приземление было жёстким», — сообщил в Twitter исполнительный директор компании SpaceX Илон Маск. По его словам, приземление было близким к задуманному плану.

 With rain showers passing over Cape Canaveral today, forecasters expect much improved conditions Tuesday, calling for a 70 percent chance of good weather for launch of SpaceX's Falcon 9 rocket at 6:05 p.m. EST (2305 GMT).
"On Tuesday, the rain and cloud cover should diminish by mid-day as the cold front pushes south," the U.S. Air Force's 45th Weather Squadron wrote in the official launch forecast. "Very strong northerly winds of 25-30 miles per hour behind the front will persist through the day. These strong winds create a concern for a liftoff wind violation. Maximum upper-level winds will be from the northwest at 90 knots near 30,000 feet."
Scattered clouds at 2,500 feet and 25,000 feet are expected at launch time, with good visibility and a temperature of 57 degrees Fahrenheit. The only concern is with strong surface winds.
On Wednesday, conditions improve more with less than a 10 percent chance of exceeding one of the launch weather rules, again due to liftoff winds.

The cryogenic liquid oxygen tanks on the first and second stages will continue to be slowly replenished until the final minutes before launch to replace propellant that gradually boils off due to the warm ambient temperatures in Florida.
 
2145 GMT (4:45 p.m. EST)
 NASA TV coverage of today's launch can be seen here at 5 p.m. EST (2200 GMT).
 
2135 GMT (4:35 p.m. EST)
 Upper level winds continue to be "red" for this evening's launch, but there is still a chance for conditions to improve later in the countdown.
Testing of the Falcon 9 rocket's flight termination system is complete at this point in the countdown, as fueling of the two-stage launcher is wrapping up.
A final weather briefing is planned at the T-minus 1 hour point in the countdown, but no problems with weather are expected this evening.
It will take about 35 minutes for the Falcon 9 rocket deliver the Deep Space Climate Observatory to its targeted escape trajectory away from Earth. DSCOVR will take 110 days to reach its operating post around the L1 Lagrange point a million miles from Earth.

2030 GMT (3:30 p.m. EST)
Fueling of the Falcon 9 rocket is underway with kerosene and liquid oxygen propellants, but officials are watching unfavorable upper level winds over Cape Canaveral.

Maximum upper level winds today are predicted to be from the northwest at 90 knots near 30,000 feet. The upper level wind conditions are currently "red" but weather balloons will continue to be released throughout the countdown to monitor for changes.

Radio checks between the rocket and the Air Force's Eastern Range have been completed, and first motion checks are coming up next in the countdown.

SpaceX is still tracking towards a 6:03pm ET liftoff of DSCOVR, but unfortunately we will not be able to attempt to recover the first stage of the Falcon 9. The drone ship was designed to operate in all but the most extreme weather. We are experiencing just such weather in the Atlantic with waves reaching up to three stories in height crashing over the decks. Also, only three of the drone ship's four engines are functioning, making station-keeping in the face of such wave action extremely difficult. The rocket will still attempt a soft landing in the water through the storm (producing valuable landing data), but survival is highly unlikely.

 It will take 110 days for DSCOVR to enter a halo orbit around the L1 point. A mid-course correction maneuver is timed for 31 hours after launch to fine-tune the spacecraft's journey toward the insertion point at L1.
DSCOVR's solar arrays should be deploying now, and the craft's magnetometer boom is to be extended on the fourth day after launch.
Then instrument calibrations are planned over the next few months. Once DSCOVR arrives at L1, the door to the EPIC camera -- which will take the full disk images of Earth -- is to be opened.
after the spacecraft is released, we have a mid-course burns that comes up after that. you have a mid-course correction, or MCC, burn that happens at about launch plus 31 hours.

February 25th, 2015          
                                 
NOAA's Deep Space Climate Observatory (DSCOVR (http://www.nesdis.noaa.gov/DSCOVR/) ) satellite is well on its way to do something epic. NOAA's spacecraft, sent to monitor space weather, will use its Earth Polychromatic Imaging Camera (EPIC) to capture the entire sunlit face of our planet and collect valuable atmospheric data. EPIC, built by Lockheed Martin (http://www.lockheedmartin.com/us.html), will show the full face of Earth in a single picture, something previously done only by the Apollo 17 astronauts and the Galileo mission on its way to Jupiter.
"EPIC will view the whole sunlit side of Earth from L-1, a point approximately one million miles away," Joe Mobilia, EPIC program manager at Lockheed Martin, told astrowatch.net (http://www.astrowatch.net/). "Today, images of Earth come from spacecraft in LEO [Low Earth Orbit] or GEO [Geosynchronous Equatorial Orbit], which only sample a portion of the planet, albeit at higher resolutions."
(https://img.novosti-kosmonavtiki.ru/234597.png)

The EPIC camera (http://www.spaceflightinsider.com/missions/earth-science/dscovr-earth-selfies-epic/) won't be turned on until the satellite reaches Lagrange point 1 (or L1 orbit) about 100 days from now, and after it completes a series of initialization checks. The first pictures of Earth will appear sometime in late July or early August, and as Mobilia noted, we should expect high-resolution snapshots.
"The detector used in EPIC is a Charge-Coupled Device (CCD), which has 2000 x 2000 pixels. The final images will have a resolution between 1.5 to 21.7 miles (25 and 35 kilometers)," Mobilia said.
(https://img.novosti-kosmonavtiki.ru/234595.jpg)

He added that EPIC will deliver images of the Earth's sunlit side at 10 different wavelengths every 1.8 hours. The scientists expect to collect approximately 10,000 images across wavelengths during its lifespan (about 2 years).

Underlining the "epicness" of the instrument, Mobilia remarked that a whole-Earth image takes approximately 16 days to capture from LEO orbit while waiting for the spacecraft to traverse across the globe. From GEO, satellites only observe a defined region since the spacecraft orbits at the same rate as the Earth, but this is great for staring at a location to observe weather patterns.
"From L-1, we have an excellent vantage point to see half the planet in one image, and this allows modelers to fill in gaps in the data. For example, ash from a volcano can be observed at the source, and distribution of the plume can be tracked over time," Mobilia said.
It's not the first time when Lockheed Martin builds an instrument to study weather and atmosphere. The company's Advanced Technology Center has built instruments looking at the atmosphere, such as the Cryogenic Limb Array Etalon Spectrometer (CLAES) on board the Upper Atmosphere Research Satellite (UARS) mission, and the High Resolution Dynamics Limb Sounder (HIRDLS) on AURA satellite.

"EPIC's instrument architecture is very similar to the instruments we have built for solar observation, such as the four telescopes that make up the AIA [Atmospheric Imaging Assembly] instrument on Solar Dynamics Observatory and the IRIS [Interface Region Imaging Spectrograph] instrument studying the sun's atmosphere. Lockheed Martin also built GLM [Geostationary Lightning Mapper], a weather-monitoring instrument on the new series of U.S. geostationary weather satellites. The first—GOES-R—will launch early next year," Mobilia added.
The DSCOVR mission is a partnership between NOAA, NASA, and the U.S. Air Force. The spacecraft was launched (http://www.spaceflightinsider.com/missions/earth-science/spacex-launches-dscovr-monitor-solar-winds/) on Feb. 11 from Cape Canaveral, Florida. It will give NOAA's Space Weather Prediction Center forecasters more reliable measurements of solar wind conditions, improving their ability to monitor potentially harmful solar activity.

NOAA's Deep Space Climate Observatory, a $340 million mission that spent more than a decade grounded in a Maryland warehouse, will begin warning forecasters of dangerous solar storms next month, giving notice of events that could disrupt air travel, radio communications, electrical grids and satellite operations.
Positioned in a halo-like orbit around the L1 Lagrange point nearly a million miles (about 1.5 million kilometers) from Earth in line with the sun, the DSCOVR spacecraft is beginning a mission of at least two years monitoring the solar wind, looking for spikes that could spark powerful geomagnetic storms at Earth.
"Even though the sun is 93 million miles away, activity on the surface of the sun can have significant impacts here on Earth," said Tom Berger, director of NOAA's Space Weather Prediction Center. "Severe space weather can disrupt power grids, marine and aviation navigation, satellite operations, GPS systems and communication technologies."
Launched from Cape Canaveral aboard a SpaceX Falcon 9 rocket in February 2015, DSCOVR is a joint project between mission leader NOAA, NASA and the U.S. Air Force. The spacecraft cruised to the L1 Lagrange point, arriving last June to begin a comprehensive engineering checkout before managers pressed the observatory into service.
NOAA announced last week that DSCOVR has completed instrument validations and will go operational July 27.
"DSCOVR will allow us to deliver more timely, accurate, and actionable geomagnetic storm warnings, giving people time to prevent damage and disruption of important technological systems," Berger said.
The early warning platform carries a Faraday Cup plasma sensor to measure the speed, density and temperature of the solar wind, and a magnetometer to measure the strength and direction of the solar magnetic field, according to NOAA.
DSCOVR also hosts two NASA-managed instruments: a camera to acquire full-disk images of the day side of Earth and a radiometer to monitor the planet's energy budget. The imager returns spectacular snapshots of Earth several times per day, and the radiometer provides data for climate change researchers.

But the chief purpose of DSCOVR is space weather forecasting, and NOAA says information collected by the satellite will help experts predict geomagnetic storms on regional scales, an improvement over the global forecasts currently issued.
"DSCOVR data will be used in a new forecast model – the Geospace Model – due to come on line this year," NOAA said in a statement. "The Geospace Model will enable forecasters to issue regional, short-term space weather forecasts for the first time, including predictions on the timing and strength of a solar storm that will impact Earth."
The spacecraft's location at L1 gives space weather forecasters, satellite operators, and infrastructure managers up to an hour of warning before the effects of a solar storm arrive at Earth.
Data from DSCOVR will be distributed to the public, along with official forecasts from NOAA.
The new observatory replaces NASA's aging Advanced Composition Explorer, which launched in 1997 and is operating well beyond its design life. DSCOVR is slated to function at least two years, but it carries enough fuel for at least five years of operations.
ACE will be kept in a backup role until at least next year, when NASA will decide on the future of the mission.
NOAA plans to have an upgraded replacement for DSCOVR ready for launch in 2022, according to the agency's budget documents.
"There is a plan for space weather continuity after DSCOVR," said Doug Biesecker, DSCOVR mission scientist at NOAA. "The baseline mission is to provide in-situ magnetic field, thermal plasma, supra-thermal ions, and a remote-sensing instrument, a coronagraph."
The coronagraph instrument is not aboard DSCOVR, and it would replace the remote imaging capability currently offered by the NASA/ESA SOHO mission at L1. A coronagraph provides scientists warning of approaching solar storms as they are triggered by massive eruptions on the sun, several days before the effects arrive on Earth.
NOAA's budget request for fiscal year 2017 asks for money for two spacecraft, two launch vehicles and two sets of instruments, and the program has won initial support from lawmakers drafting the agency's final budget. The first of the satellites would be launched in 2022 at the end of DSCOVR's projected life.
The DSCOVR mission had to wait nearly two decades since its inception after the project became tied up in political wrangling in Washington.
First proposed by then-Vice President Al Gore in 1998, the mission was supposed to broadcast live views of Earth from a distant vista a million miles away for live streaming on the Internet. Gore believed the mission — which Gore named Triana after one of the sailors on Columbus's 1492 voyage to the new world — would raise awareness of environmental issues, and scientists developed instruments to collect data on the planet's climate.
But Republican lawmakers decried the mission as Gore's pet project, and Congress ordered NASA to stop work on Triana in late 1999. The space agency transferred the nearly-complete satellite into storage in November 2001 after President George W. Bush took office.
NASA formally canceled the mission in 2005 after renaming Triana as DSCOVR. The space agency said the spacecraft, which was originally designed to launch on the space shuttle, could not fit on one of the shuttle's remaining missions.
NOAA took charge of the mission in 2008 to replace ACE, and the U.S. Air Force signed on to pay for DSCOVR's launch on a Falcon 9 rocket.

 29 июня, 8:32 UTC+3

 Аппарат начнет передавать на Землю данные с предсказаниями времени и силы солнечных бурь
 
ВАШИНГТОН, 29 июня. /Корр. ТАСС Иван Лебедев/. Американский космический аппарат, который должен следить за солнечной активностью и предупреждать о геомагнитных бурях, через месяц приступит к полномасштабной работе.
Как сообщило NASA, орбитальная обсерватория, сложное и длинное название которой складывается в аббревиатуру DSCOVR ("Дискавер"/"Открытие" ) , будет введена в строй 27 июля.
Ее главная задача - наблюдение за "космической погодой", которая зависит от "порывов" солнечного ветра (потоков ионизированных частиц), взаимодействующего с магнитосферой Земли. "Возникающие от этого сильные геомагнитные бури могут нарушить работу линий электропередачи, авиационных и морских навигационных приборов, спутников связи, систем глобального позиционирования и телекоммуникационных систем", - отметил ведущий сотрудник Национального управления США по изучению океана и атмосферы Том Бергер.
Он возглавляет Центр прогнозирования космической погоды, который вместе с NASA и ВВС США подготовил этот проект стоимостью $340 млн. "DSCOVR позволит нам давать более оперативные и точные предупреждения о геомагнитных бурях, и благодаря этому у людей будет время, чтобы принять меры и не допустить нанесения ущерба важным техническим системам", - пояснил специалист.
Аппарат был запущен в феврале 2015 года с помощью ракеты-носителя Falcon-9 с базы ВВС, расположенной рядом с космодромом на мысе Канаверал (штат Флорида), а в июне вышел в район первой точки Лагранжа в системе Солнце-Земля, где и будет находиться во время своей миссии. С тех пор ученые настраивали и тщательно проверяли все его приборы и механизмы, прежде чем дать ему команду начать работу.
DSCOVR оснащен четырьмя приборами, в том числе датчиком для измерения скорости, плотности и температуры солнечного ветра и магнетометром для определения силы и направления магнитного поля Солнца. Кроме того, на нем установлены фотокамера, с помощью которой сотрудники NASA рассчитывают получить новые снимки Солнца, а также радиометр, чтобы следить за расходованием энергии этого небесного тела.
По плану аппарат должен проработать в космосе как минимум два года, но запаса топлива у него хватит на пять лет. Данные, которые он вскоре начнет передавать на Землю, используют при подготовке прогнозов "космической погоды" нового типа. Как сообщило Национальное управление США по изучению океана и атмосферы, "в них впервые будут содержаться предсказания времени и силы солнечных бурь, которые окажут воздействие на Землю".

DSCOVR's computer may be suffering fr om radiation-induced glitches, months after it became the primary sentinel for incoming solar storms.

DSCOVR monitors space weather from a perch about 1.5 kilometres from Earth.
                        
A US space-weather satellite that is supposed to alert Earth to incoming solar storms has temporarily dropped offline five times in the year since it became operational. Its onboard computer may be experiencing hiccups caused unexpectedly by galactic cosmic rays.
The Deep Space Climate Observatory (DSCOVR) went out of action most recently on 11 October. In each case, it unexpectedly entered a 'safe hold' in which scientific data stopped flowing and engineers had to scramble to try to recover the spacecraft. In total, DSCOVR's space-weather forecasting instruments have been offline for more than 42 hours since 28 October 2015, when the US National Oceanic and Atmospheric Administration (NOAA) took the spacecraft over from NASA, which built and launched it.
Each outage lasts for only a few hours, and the total downtime amounts to 0.48% of its time in space — well below NOAA's requirement that the spacecraft operate at least 96% of the time. The 11 October outage did not significantly affect predictions of a minor geomagnetic storm that arrived a few days later, says Robert Rutledge, head of the forecast office at NOAA's Space Weather Prediction Center in Boulder, Colorado (http://www.swpc.noaa.gov/).
But the outages mean that DSCOVR could be offline when a major solar storm erupts, leaving Earth essentially blind to the incoming onslaught. "Are they problematic? Yes," says Douglas Biesecker, a solar physicist at the Boulder centre.

Storm warning

Other heliophysics spacecraft monitor solar eruptions, but DSCOVR delivers unique information from its location at the gravitationally stable L1 point, about 1.5 million kilometres from Earth in the direction of the Sun. The spacecraft's instruments directly measure the speed, magnetic field and other properties of the charged particles streaming off the Sun. Those data translate into better forecasts of what could happen when a solar storm hits Earth (http://www.nature.com/news/us-sharpens-surveillance-of-crippling-solar-storms-1.20630), such as disruptions to satellite electronics or fluctuations in electrical power grids.
DSCOVR is NOAA's main tool for forecasting space weather, but it began life as Triana (http://www.nature.com/news/al-gore-s-dream-spacecraft-gears-up-for-launch-1.16711), a NASA Earth-observing spacecraft built in the late 1990s to gaze constantly at the planet. A pet project of Al Gore, then the US vice-president, Triana was shelved in 2001, then repurposed in 2008 for NOAA's space-weather needs. "It was never designed from the beginning to be a space-weather satellite," says Steven Clarke, head of NASA's heliophysics division in Washington DC.
The satellite launched on 11 February 2015 and experienced its first outage four months later, when its onboard computer spontaneously rebooted. On average, the safe holds happen every 74 days, but two came just eight days apart. They are not correlated with solar storms.
A NASA internal review board convened to study the problem could not definitively pinpoint the cause, but concluded that it was most likely to be galactic cosmic rays randomly striking the spacecraft, causing high-energy ionization that reboots the computer. The computer, which was built by NASA in 2000, contains a processor card that is similar to those flying aboard many other missions and is meant to withstand the radiation hazards of deep space.

Knowledge gap

NOAA does have a back-up data stream, from the Advanced Composition Explorer (ACE) spacecraft that is also orbiting the L1 point. That was the primary source of solar-wind data until NOAA forecasters switched to DSCOVR in July. But ACE is 19 years old, and intense solar storms can swamp its forecasting instruments, causing problems when data are needed the most.
NOAA has requested an extra US$1.5 million from Congress to improve how it handles DSCOVR data, including its responses to the outages. The satellite is supposed to last until 2022, when a follow-up mission is slated for launch. Historically, NOAA has cobbled together its space-weather observations wh ere and when it could, but the US government is starting to demand a more coherent approach. On 13 October, President Barack Obama signed an executive order (https://www.whitehouse.gov/the-press-office/2016/10/13/executive-order-coordinating-efforts-prepare-nation-space-weather-events) that, among other things, requires NOAA to "ensure the continuous improvement of operational space weather services".

ЦитироватьNASA обнаружило странные вспышки Земли
Камера NASA захватила неожиданные вспышки света, отражающиеся от нашей планеты. Как написали обозреватели из агентства, ставя под сомнение источник этих огней, ученые расшифровали крошечную причину больших отражений: высотных горизонтально ориентированных кристаллов льда.

 Инструмент NASA Earth Polychromatic Imaging Camera (EPIC) на борту DSCOVR принимает почти почасовые изображения солнечной планеты от ее места между Землей и Солнцем. Александр Маршак, заместитель проектного сотрудника DSCOVR в Центре космических полетов им. Годдарда в Гринбелте, штат Мэриленд, впервые заметил вспышки света, иногда появляющиеся над океанами, когда он просматривал изображения EPIC этого дня.

Вспышки света, отраженные от океанов, могли иметь простое объяснение. Маршак сказал: "Солнечный свет поражает гладкую часть океана или озера и отражает непосредственно обратно к сенсору, подобно съемке флеш-картины в зеркале".

Еще одна особенность данных EPIC помогла подтвердить, что вспышки были с большой высоты, а не просто над водой на земле. Два канала на приборе предназначены для измерения высоты облаков, и когда ученые пошли к данным, они обнаружили высокие перистые облака, от 3 до 5 миль (5-8 км), где были найдены блики.

Обнаружение таких бликов с гораздо большего расстояния, чем в этом случае, может быть использовано другими космическими аппаратами для изучения экзопланет. Однако, Маршак сейчас исследует, насколько распространены эти горизонтальные частицы льда, и являются ли они достаточно распространенными, чтобы измерить влияние того, сколько солнечного света проходит через атмосферу. Если это так, это функция, которая может быть включена в компьютерные модели того, сколько тепла достигает и покидает Землю.

WASHINGTON — A joint NASA/NOAA spacecraft that monitors space weather and provides imagery of Earth has been offline for more than a week because of a problem with its positioning system.

The Deep Space Climate Observatory, or DSCOVR, spacecraft went into a "safehold" June 27, interrupting its science observations from its perch at the Earth-sun L-1 Lagrange point, 1.5 million kilometers from the Earth in the direction of the sun.

NOAA spokesman John Leslie said July 5 that engineers placed the spacecraft into safehold to "first diagnose and then work to fix a technical issue in the system that maintains the satellite's position." While that work is underway, he said, the spacecraft is not returning data.

The primary mission of DSCOVR, launched in February 2015, is to monitor solar wind conditions, providing advance notice of space weather events. While DSCOVR is in safehold, Leslie said NOAA's Space Weather Prediction Center will instead rely on data from the Advanced Composition Explorer (ACE) and Solar and Heliophysic Observatory (SOHO) spacecraft, which, like DSCOVR, are at the Earth-sun L-1 point, as well as instruments on weather satellites in geostationary Earth orbit.

DSCOVR has suffered a number of safeholds in the past, but those typically have lasted only a matter of hours. Engineers speculated that those earlier safeholds were caused by cosmic ray hits on spacecraft electronics. Leslie didn't give a timetable for resuming normal operations of DSCOVR.

While DSCOVR's primary mission is space weather monitoring, the spacecraft is perhaps best known for an Earth-facing camera called Earth Polychromatic Imaging Camera (EPIC). That camera takes full-disk images of the Earth that can be used for global monitoring of atmospheric ozone and aerosols, as well as clouds and vegetation.

EPIC dates back to the original mission for DSCOVR more than 20 years ago. NASA proposed the mission, then called Triana, at the request of Vice President Al Gore to provide that full view of the Earth. The mission was put on hold early in the administration of President George W. Bush, with the spacecraft put into storage. The Obama administration resurrected the mission under the DSCOVR name and with a new emphasis on space weather monitoring.

The Trump administration, though, proposed terminating EPIC operations. Its NASA budget requests for fiscal years 2018 and 2019 included no funding for EPIC, proposals that did not affect the overall DSCOVR mission, funded by NOAA. Congress rejected those proposals, explicitly including funding for DSCOVR operations in their final appropriations bills.

NASA did not repeat that effort to end funding of DSCOVR in its fiscal year 2020 budget request. The agency's budget proposal sought $1.7 million for DSCOVR operations, the same amount it received in 2018.

Back to the moon soon

Цитата: undefinedSpaceX запустила свою первую межпланетную миссию почти семь лет назад (11 февраля 2015 года, прим. мое). После того, как вторая ступень ракеты Falcon 9 завершила длительный запуск, чтобы выйти на переходную орбиту, Космическая климатическая обсерватория - DSCOVR NOAA начала свое путешествие к точке Лагранжа Солнце-Земля более чем в 1 миллионе км от Земли.

К этому моменту вторая ступень ракеты Falcon 9 была достаточно далеко, чтобы у нее не хватило топлива для возвращения в атмосферу Земли. Ей также не хватало энергии, чтобы избежать гравитации системы Земля-Луна, поэтому с февраля 2015 года она движется по несколько хаотичной орбите.

Сейчас, по данным наблюдателей, орбита отработанной второй ступени находится на пути к пересечению с Луной. По словам Билла Грея, который пишет широко используемое программное обеспечение Project Pluto для отслеживания околоземных объектов, астероидов, малых планет и комет, такое воздействие может произойти в марте.

Ранее в этом месяце Грей обратился с призывом к астрономам-любителям и профессионалам провести дополнительные наблюдения за ступенью, которая,  летит в космосе. С учетом этих новых данных Грей теперь считает, что разгонный блок Falcon 9, скорее всего, столкнется с обратной стороной Луны, вблизи экватора, 4 марта.

Остаются некоторые неясности. Поскольку объект кувыркается, трудно точно предсказать влияние солнечного света, "давящего" на ступень ракеты и, таким образом, вносящего небольшие изменения в ее орбиту. "Эти непредсказуемые эффекты очень малы", - пишет Грей. Но они будут накапливаться в период до 4 марта, и необходимы дальнейшие наблюдения, чтобы уточнить точное время и место воздействия.

Эта информация важна, поскольку она позволит спутникам, находящимся в настоящее время на орбите Луны, в том числе орбитальному аппарату НАСА LRO и индийскому космическому аппарату "Чандрайан-2", собирать наблюдения за ударным кратером. С помощью миссии LCROSS НАСА намеренно сбросило отработавшую верхнюю ступень ракеты на Луну в 2009 году с этой целью. Хотя ученые больше всего стремятся понять наличие льда на полюсах Луны, возможность наблюдать подземный материал, выброшенный в результате удара ракеты Falcon 9, все еще может предоставить некоторые ценные данные.

Сухая масса второй ступени Falcon 9 составляет около 4 метрических тонн, и она должна ударить по Луне со скоростью около 2,58 км/с.

Вполне вероятно, что это будет первый случай, когда часть космического оборудования непреднамеренно ударится о Луну. Как правило, во время межпланетных полетов разгонный блок ракеты выводится на гелиоцентрическую орбиту, удаляя ее от Земли и Луны.
